Like many world leaders throughout history, the 45th President of the United States survives on very little sleep, just four hours a night, he told Playboy in 1990.

Close advisers say they often get calls from him at 1.30am or 4.30am during the night. According to the NYT, he usually retreats to his residence alone after 16-hour days in the West Wing to tweet, vent and recharge. The newspaper also published embarrassing anecdotes about him watching TV in his bathrobe and staff meeting in the dark because they couldn’t find the light switches, stories Mr Trump has blasted as “total fiction”.

2. NO ALCOHOL, CIGARETTES OR COFFEE

Despite thriving on a high-pressure environment, Mr Trump does not drink alcohol, coffee or tea, nor does he smoke, although he enjoys the occasional Diet Coke (real Coke on treat days) and Virgin Bloody Mary. This is said to be because he lost his brother Fred to alcoholism. He did, however, introduce Trump Vodka in 2006 and bought a winery in Virginia in 2011, Trump Vineyard Estates, now owned by his son Eric.

3. A MEAT AND POTATOES MAN

He may be a billionaire, but Mr Trump is a man of the people when it comes to his partiality to takeaway in the form of KFC, McDonald’s Big Macs and fries. When he’s slimming, he’ll pull the bun off his burger or eat just a pizza’s toppings to save calories. An aide told Axios he’s cut down on the junk food since entering the White House, sticking to his beloved steak — which his butler told the New York Times he likes so well-done it “would rock on the plate” — crab or shrimp, with a side of vegetables or Cobb salad. He also loves classics including meatloaf, caesar salad and spaghetti, and snacks on original Lay’s potato chips, vanilla Keebler Vienna Fingers. His preferred treats are cherry vanilla ice cream and See’s candies, but he doesn’t eat Oreos since they began using crops grown in Mexico.

4. A STICKLER FOR HYGIENE

Mr Trump is a self-confessed “germophobe” who has called the practice of shaking hands “barbaric”, because you can catch flu and “all sorts of things”. In The Art of the Comeback, he wrote that he washes his hands “as often as possible”, and he reportedly will not press the ground floor button in a lift because it is the most touched.

Part of the reason Mr Trump gives for his love of fast food is the restaurants’ hygiene standards. “I’m a very clean person,” he told CNN. “I like cleanliness, and I think you’re better off going there than maybe someplace that you have no idea where the food’s coming from.”

He made headlines for eating a pizza slice with a knife and fork in Times Square and attacked his primary race rival, John Kasich of Ohio, for his table manners, telling a crowd: “I’ve never seen a human being eat in such a disgusting fashion!”

Any negative polls are fake news, just like the CNN, ABC, NBC polls in the election. Sorry, people want border security and extreme vetting.

The President has a love-hate relationship with the media, watching hours of cable TV, starting with MSNBC’s Morning Joe from 6am, Fox & Friends from 7am, a little CNN and Meet the Press on Sundays.

He is also handed a stack of newspaper clippings about him each day. The news addict regularly fires out angry tweets based on what he’s seen, and recently upgraded the flat-screen TV in his private dining room so he can watch through lunch. He also loves Access Hollywood and 60 Minutes. While he prefers television to newspapers, he also reads the NYT, NY Post and Wall Street Journal, scrawling notes for staffers with a black Sharpie. This is reflected in his favourite books and films, with the tycoon telling Us Weekly he favours histories and biographies, and the movie Citizen Kane. about a wealthy newspaper publisher. The New Yorker called the former Apprentice star a “TV-reality President” trapped in a world of breaking news in which “every hiccup is a crisis” and every criticism a disaster.

The failing @nytimes writes total fiction concerning me. They have gotten it wrong for two years, and now are making up stories & sources!

Known for his bouffant hair, cut by his wife, Mr Trump has complained that environmentalists are trying to ruin his hairspray. “You’re not allowed to use hairspray any more because it affects the ozone, you know that, right?” he asked an audience of coal miners at a rally in Charleston, West Virginia, sweeping back his hair to show it was real. “Hairspray’s not like it used to be, it used to be real good. Today you put the hairspray on and it’s good for 12 minutes.”

He once reportedly asked for a cashmere sweater to be cut off him with scissors during a Vanity Fair shoot to avoid messing up his ‘do. While no one knows the truth about his day-glo skin, many suspect it is down to spray tanning, make-up or sun-bed use, with telltale white circles visible around his eyes. The most likely culprit is his longtime friend Steve Hilbert, former CEO of a tanning company.

6. HE DOESN’T GET MUCH EXERCISE

Mr Trump loves all sports, captaining various high school teams and managing a professional football team in the USFL league. But these days, he only really plays golf, owning 17 clubs across the world from Miami and New York to Ireland and Scotland.

The President doesn’t even exert himself much in daily life either, since he apparently has a phobia or stairs and ramps, using elevators and lifts to travel from his work to home in Trump Tower. He’s not worried, either. “All my friends who work out all the time, they’re going for knee replacements, hip replacements — they’re a disaster,” he has said.
